Wallpaper with dynamic views [PLUS]

I would like to prepare a creator for decorative wallpapers. I have purchased the "Plus" supplement. As I set dynamic views on eg 270x300cm, the canvas is very large and you can not do anything.

I would like to get an effect similar to this:

I would like the canvas to be constant and to change the proportions of the picture inside it.
